In August and September of 2018, the joint field study on the basis of Research Station RAS in Bishkek city with participation of staff members of GIN RAS, Moscow (Alekseev D.V.), St. Petersburg State University (Hudolya A.K., Moskalenko A.N., Kushnareva A.V.) and A.P. Karpinsky Russian Geological Research Institute (VSEGEI) (Tolmacheva T.Yu.) was conducted. This works were aimed to study stratigraphy, geochronology and structural evolution of Precambrian and early Paleozoic complexes of the Northern Tien Shan. As a result, the detailed structural characteristic of a mesoproterozoic Kochkor complex and its analogs in Talas district, early Paleozoic ensembles of Aktyuz, Makbalsk and Talas complexes were obtained and conodont fauna age of siliceous and volcanic series of an early Paleozoic Kyrgyz Terskeysky sutura zone were specified. In order to conduct geochronological, paleontologic, geochemical and structural, geological studies the set of samples was collected and passed to GIN RAS laboratories, VSEGEI and St.Petersburg State University for processing.
